SPECIFICATION forming part of Letters Patent No. 332,517, dated December15, 1885.

Application filed October 17, 1885. Serial No. 180,122. (No model.)

To an whom it may concern:

Be it known that I, A. FRANK HARRELL, a citizen of the United States,residing at Terrell, in the county of Kaufman and State of Texas, haveinvented certain new and useful Improvements in Motors, of which thefollowing is a specification.

My invention relates to motors designed more particularly for runningsewing machines and churns and other light machinery, the object beingto provide a device of this character which shall be simple in itsconstruction, effective in its operation, strong and durable, and onethat is not likely to get out of order.

\Vith these ends in view the invention consists in the improvedconstruction and combinations of parts, hereinafter fully described, andpointed out in the claims.

In the drawings, Figure l is a side elevation of a motor embodying myinvention. Fig. 2 is a plan view, and Figs. 3 and 4 are sectional views.

Corresponding parts in the several figures are denoted by the sameletters of reference.

Referring to the drawings, A represents a supporting frame, at one endof which is located a shaft, B, having bearing in the sides of thesupporting frame. One end of this shaft B extends beyond thesupporting-frame, and is squared, as shown, to receive a key. Upon theshaft B is rigidly secured at one end a steel spring, 0, which issecured to the supporting-frame at its other end. Mounted on the shaftB, adjacent to the spring 0, is a spurwheel, D, which is rigidly securedto said shaft. Adjacent to the spur-wheel D, on the shaft B, is aratchet-wheel, E, and adapted to engage the same is a pawl, a, which isheld in engagement with the ratchet-wheel by means of a spring, Z). Itwill thus be seen that if the shaft B is turned by means of a key, itwill be wound upon the shaft, and that its unwinding will be preventedby the ratchetwheel and pawl which engages therewith. The pawl ispivoted to the wheel D, so that when the shaft turns by the force of thespring the ratchet-wheel turns, and thereby imparts motion to thespur-wheel D.

E represents a shaft, which is located just above the spur-wheel D, andwhich has mounted thereon a lantern-wheel, c, to mesh with thespur-wheel D. Just above the shaft E is another shaft, F, which hasmounted on it a a lantern-wheel, e, to mesh with a spnr-wheel, f, on theshaft E, and on the shaft F is a spurwheel, 9, which meshes with alantern-wheel, h, on a shaft, H, located in front ofthe shaft F.

I represent an escapementwheel on the shaft F, and located adjacentthereto, and adapted to engage it is a pallet, J, having an extendedarm, K,. on which is a movable weight, whereby the speed of the motormay be regulated by moving it to or from the escapement-wheel. Securedto the outer end of the extended arm is a cord, L, which connects with apedal, by means of which the device may be stopped.

Journaled in the front of the frame is a rockshaft, M, upon one end ofwhich is mounted an arm, N, to the outer cndof which a dasher may beattached, and extending upwardly from said rock-shaft is an arm, 0,which is connected to the crank-shaft by an arm, P, whereby therock-shaft will be oscillated.

In using the device for running sewingmachines a pulley might be placedon the crank-shaft, and connected with a pulley on the rock-shaft by abelt and the rock-shaft connected with the sewing-machine.

Having thus described my invention, what I claim is 1. Thecom.bination,with asupporting-frame and a shaft having bearing therein,of a spring, a spur wheel, a ratchet wheel, a pawl, and spring to engagetherewith, a shaft having an escapement-wheel thereon, intermediategearing between the spur-wheel and escapementwheel, a pallet having anextension, a movable weight thereon, a treadle, and a cord connectingthe extension and treadle, as set forth.

2. The combination, with a supportingframe, of a train ofspring-actuated gearing, a crank-shaft, a rock-shaft having an arm,connections between the crank and rock shafts, and means, substantiallyas described, for regulating the speed of the device, substanstantiall yas set forth.

3. lhe eombination, with a supportingshaft connected with saidarm, andan arm 10 frame, a shaft mounted therein, a spring, a on the rock-shaft,as set forth. spur-wheel, a ratchet-wheel, a pawl secured In testimonywhereof I 211362: mysignature in to the spur and engaging the ratchetWheel, presence of two Witnesses.
